摘要:

A total of 251 patients with epithelial ovarian cancer (EOC) treated between 2002 and 2008 was retrospectively analyzed to investigate the long-term outcomes and prognostic factors of these patients, particularly those who underwent primary debulking surgery followed by platinum-based chemotherapy. Clinico-pathological parameters, including progression-free survival (PFS) and overall survival (OS), were also analyzed. The median follow-up period from the end of initial treatment to June 2010 was 58 months. The three-year PFS rate was 61.7% for International Federation of Gynecology and Obstetrics (FIGO) I–II, 19.9% for FIGO III–IV, and 33.9% for all stages. By comparison, the five-year PFS rate was 44.6% for FIGO I–II, 17.7% for FIGO III–IV, and 28.3% for all stages. The three-year OS rate was 67.9% for FIGO I–II, 41.7% for FIGO III–IV, and 50.2% for all stages. The five-year OS rate was 52.7% for FIGO I–II, 30.8% for FIGO III–IV, and 39.2% for all stages. Univariate analysis revealed that advanced FIGO stage, serum CA125, and suboptimal debulking were significant factors affecting PFS and OS. In multivariate analysis, PFS was significantly influenced by FIGO stage and suboptimal debulking. However, OS was significantly influenced by advanced FIGO stage only. Our study confirms the efficacy of surgery followed by platinum-based chemotherapy for EOC. FIGO stage is considered as one of the most reliable predictors of the prognosis of patients with EOC.

摘要:

Mature T-cell lymphoid malignancies comprise a group of heterogeneous diseases that vary in clinicopathological features, biological behavior, treatment response, and prognosis. Bone marrow (BM) infiltration is more commonly present in mature T-cell lymphoid malignancies compared with their B-cell counterparts and hence important for differential diagnosis. In this study, clinical characteristics and prognostic factors were analyzed in 225 patients with mature T-cell lymphoid malignancies treated in a single institution. These included 29 cases of T-cell lymphoproliferative disorders (T-LPD, all with BM infiltration) and 196 cases of T-/natural-killer-cell lymphoma (T/NKCL, 56 with BM infiltration and 140 without BM infiltration). The estimated 5-year overall survival (OS) rates of T-LPD and T/NKCL were 96.6% and 37.3%, respectively. T-LPD patients were less likely to exhibit poor performance status, advanced disease stage, presence of B symptoms, or abnormal level of serum β-2 microglobulin. With similar pathological characteristics, T/NKCL patients with BM infiltration showed significantly lower response rates and shorter OS than those without BM infiltration (P = 0.0264 and P<0.0001, respectively). Multivariate analysis indicated that poor performance status, advanced disease stage, elevated serum lactate dehydrogenase level, and BM involvement were independent unfavorable prognostic factors. The Glasgow Prognostic Score may be more efficient than the International Prognostic Index in predicting disease outcome in T/NKCL. In conclusion, clinical characteristics may be useful in more effectively stratifying patients with mature T-cell lymphoid malignancies.

《医学前沿(英文)》 2017年 第11卷 第2期   页码 229-238 doi: 10.1007/s11684-017-0506-y

摘要:

A CALLG2008 protocol was developed by the Chinese Acute Lymphoblastic Leukemia Cooperative Group for adult acute lymphoblastic leukemia (ALL). We retrospectively analyzed 153 newly diagnosed adult patients with Philadelphia chromosome (Ph)-positive ALL enrolled into imatinib (400 mg/d) plus CALLG2008 regimen between 2009 and 2015. The median age was 40 years (range, 18–68 years), with 81 (52.3%) males. The overall hematologic complete remission (CR) rate was 96.7% after induction. With a median follow-up of 24.2 months, the estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 49.5% (95% confidence interval (CI): 38.5%–59.5%) and 49.2% (95% CI: 38.3%–59.2%), respectively. Fifty-eight (36 with haploidentical donor) patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in first CR. Among the patients in CR1 after induction, both the 3-year OS and EFS were significantly better in the allo-HSCT group than in the without allo-HSCT group (73.2%, 95% CI: 58.3%–83.5% vs. 22.2%, 95% CI: 8.7%–39.6% and 66.5%, 95% CI: 50.7%–78.2% vs. 16.1%, 95% CI: 5.1%–32.7%, respectively). Multivariate analysis showed that allo-HSCT and achievement of major molecular response were associated with favorable OS or EFS independently. Interestingly, in the allo-HSCT cohort, the donor type (haploidentical versus matched donors) had no significant impact on EFS or OS. All these results suggested that imatinib plus CALLG2008 was an effective protocol for Ph-positive ALL. Haploidentical donors can also be a reasonable alternative expedient donor pool.

Serum carbohydrate antigen (CA) 19-9 as a prognostic factor in cholangiocarcinoma: A meta-analysis

Shang-Long LIU, Zi-Fang SONG, Qing-Gang HU, Shao-Bo HU, Jun LI, Qi-Chang ZHENG, Duo SHAN,

《医学前沿(英文)》 2010年 第4卷 第4期   页码 457-462 doi: 10.1007/s11684-010-0240-1

摘要: This study was performed to determine the prognostic role of preoperative serum carbohydrate antigen (CA) 19-9 levels in the survival of patients with cholangiocarcinoma. Articles published up to June 1, 2010 that evaluated preoperative CA19-9 levels and the prognosis of cholangiocarcinoma were collected for meta-analysis. The required information for calculating individual relative risk (RR) was extracted from the studies, and a combined overall RR was estimated. Nine eligible studies were included. One study dealt with extra-hepatic cholangiocarcinoma, while the other eight studies analyzed intra-hepatic cholangiocarcinoma. The mean methodological quality score was 74.1%, ranging from 65.5% to 82.5%. The overall RR for the nine studies was 1.28 (95% confidence interval= 1.10–1.46), and the Z-score for overall effect was 13.83 (<0.001). The association between serum CA19-9 level and lymph node involvement was also assessed. The combined RR was 1.471 (95% confidence interval= 0.411–5.264) and Z-score for overall effect was 0.59 ( = 0.553). CA19-9 levels were associated significantly with the prognosis of patients with cholangiocarcinoma. This meta-analysis shows that elevation of preoperative CA19-9 levels is correlated with a poor prognosis of patients with cholangiocarcinoma. However, larger scale and randomized studies are needed to draw a more substantive conclusion.

《工程管理前沿(英文)》 2020年 第7卷 第3期   页码 323-334 doi: 10.1007/s42524-020-0121-5

摘要: Condition-based maintenance (CBM) detects early signs of failure and dictates when maintenance should be performed based on the actual condition of a system. In this paper, we first review some of the recent research on CBM under various physical structures and signal data. Then, we summarize several kinds of prognostic models that use monitoring information to estimate the reliability of complex systems or products. Monitoring information also facilitates operational decisions in production planning, spare parts management, reliability improvement, and prognostics and health management. Finally, we suggest some research opportunities for the reliability and operations management communities to fill the research gap between these two fields.

Four-protein model for predicting prognostic risk of lung cancer

《医学前沿(英文)》 2022年 第16卷 第4期   页码 618-626 doi: 10.1007/s11684-021-0867-0

摘要: Patients with lung cancer at the same stage may have markedly different overall outcome and a lack of specific biomarker to predict lung cancer outcome. Heat-shock protein 90 β (HSP90β) is overexpressed in various tumor cells. In this study, the ELISA results of HSP90β combined with CEA, CA125, and CYFRA21-1 were used to construct a recursive partitioning decision tree model to establish a four-protein diagnostic model and predict the survival of patients with lung cancer. Survival analysis showed that the recursive partitioning decision tree could distinguish the prognosis between high- and low-risk groups. Results suggested that the joint detection of HSP90β, CEA, CA125, and CYFRA21-1 in the peripheral blood of patients with lung cancer is plausible for early diagnosis and prognosis prediction of lung cancer.

摘要:

Midline2 (MID2) is an ubiquitin-conjugating E2 enzyme linked to tumor progression and a novel interacting partner of breast cancer 1, early-onset (BRCA1). However, the role of MID2 in breast cancer remains unknown. This study investigated the expression, prognostic value, and role of MID2 in breast cancer. The expression of MID2 mRNA and protein was significantly upregulated in breast cancer tissue and established cell lines compared with that in normal breast epithelial cells and paired adjacent non-tumor tissue (P<0.001). Immunohistochemical analysis demonstrated that MID2 was overexpressed in 272 of 284 (95.8%) paraffin-embedded, archived breast cancer tissue. Moreover, MID2 expression increased with advanced clinical stage (P<0.001). High MID2 expression was significantly associated with advanced clinical stages and T, N, and M staging (all P<0.05). Univariate and multivariate analyses indicated that high MID2 expression was an independent prognostic factor for poor overall survival in the entire cohort (93.73 vs. 172.1 months; P<0.001, log-rank test) and in subgroups with stages Tis+ I+ II and III+ IV. Furthermore, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide colony formation, and anchorage-independent growth ability assays were conducted. Results showed that siRNA silencing of MID2 expression significantly reduced MCF-7 and MDA-MB-231 cell proliferation in vitro and blocked the growth of MDA-MB-231 cell xenograft tumors in vivo (P<0.05). This study indicated that MID2 may be a novel prognostic marker and interventional target in breast cancer.

ACSL5, a prognostic factor in acute myeloid leukemia, modulates the activity of Wnt/-catenin signaling

《医学前沿(英文)》 2023年 第17卷 第4期   页码 685-698 doi: 10.1007/s11684-022-0942-1

摘要: Acyl-CoA synthetase long chain family member 5 (ACSL5), is a member of the acyl-CoA synthetases (ACSs) family that activates long chain fatty acids by catalyzing the synthesis of fatty acyl-CoAs. The dysregulation of ACSL5 has been reported in some cancers, such as glioma and colon cancers. However, little is known about the role of ACSL5 in acute myeloid leukemia (AML). We found that the expression of ACSL5 was higher in bone marrow cells from AML patients compared with that from healthy donors. ACSL5 level could serve as an independent prognostic predictor of the overall survival of AML patients. In AML cells, the ACSL5 knockdown inhibited cell growth both in vitro and in vivo. Mechanistically, the knockdown of ACSL5 suppressed the activation of the Wnt/β-catenin pathway by suppressing the palmitoylation modification of Wnt3a. Additionally, triacsin c, a pan-ACS family inhibitor, inhibited cell growth and robustly induced cell apoptosis when combined with ABT-199, the FDA approved BCL-2 inhibitor for AML therapy. Our results indicate that ACSL5 is a potential prognosis marker for AML and a promising pharmacological target for the treatment of molecularly stratified AML.

摘要: The authors performed a meta-analysis of case-control studies that addressed whether reproductive factors and oral contraceptive use were associated with breast cancer by searching the MEDLINE, PubMed, Proquest, Embase, ScienceDirect, African Healthline, BMJ Health Intelligence and Chinese Periodical net databases for all English-language and Chinese-language papers published from January 1, 1997 to December 31, 2007. A total of 15 studies calculating pool ORs indicated that menopausal age >50yr [odds ratio (OR), 1.39; 95% confidence interval (CI), 1.22―1.57] and oral contraceptive use (OR, 2.12*, “*”: summary OR was adjusted; 95% CI, 1.24―3.62) were correlated with the increase in breast cancer risk while the summary OR based on number of full-term pregnancies ≥1 (OR, 0.63*; 95% CI, 0.60―0.68) and breast-feeding (OR, 0.76; 95% CI, 0.64―0.90) indicated no association with breast cancer risk. The correlation was statistically significant. Menopausal age >50yr and oral contraceptive use are positively correlated with an increase in breast cancer risk while breast-feeding and number of full-term pregnancies ≥1 are protective factors.

摘要:

We evaluated the outcomes of chronic myeloid leukemia (CML) patients in three clinical phases, namely, chronic (CP), accelerated (AP), and blast (BP) phases, receiving imatinib treatment. The single-institution treatment experiences of Chinese patients with CML were presented. A total of 275 CML patients (CP, 210; AP, 24; and BP, 41) who received imatinib between February 2001 and April 2008 were enrolled in this study. We evaluated the responses (hematologic, cytogenetic, and molecular), overall survival (OS), treatment event-free survival (EFS), and prognostic factors of outcome. At the cut-off point, the complete cytogenetic response (CCyR) and complete molecular response rates of patients in the CP were 84.7% and 61.9%, respectively, which were significantly higher than those of patients in the AP (50% and 29.1%, respectively, both P<0.001) and BP (24.3% and 9.7%, respectively, both P<0.001). The estimated five-year OS and five-year EFS rates were 93.2% and 86.4% for CP patients, as well as 64.5% and 50.9% for AP patients, which were significantly higher than those for BP patients (P<0.001). In CP patients, univariate analysis revealed that early treatment with imatinib, achieving CCyR within 12 months, additional cytogenetic abnormalities, and kinase domain mutations were associated with the treatment outcome. More patients are needed to carry out multivariate analysis.

摘要:

The risk factors, especially laboratory indicators, of prognosis after acute kidney injury (AKI) remain unclear. We conducted a retrospective survey of Chinese People’s Liberation Army General Hospital from January 1, 2012 to December 31, 2012 according to the AKI diagnosis standard issued by Kidney Disease Improving Global Outcomes. The epidemiological features and factors influencing hospital mortality and renal function recovery were evaluated through logistic regression analysis. Among 77 662 cases of hospitalized patients, 1387 suffered from AKI. The incidence rate and mortality of AKI were 1.79% and 14.56%, respectively. Multivariate logistic regression analysis revealed that high AKI stage, age greater than 80 years, neoplastic disease, low cardiac output, increased white blood cell count, and decreased platelet count and serum albumin levels were the risk factors affecting the mortality of AKI patients. Conversely, body mass index between 28 and 34.9 was a protective factor. Increased AKI stage, tumor disease, post-cardiopulmonary resuscitation, and RRT were the risk factors of renal function recovery upon discharge. In addition to traditional risk factors, white blood cell count, platelet count, albumin, and BMI were the predictors of the mortality of AKI patients. No laboratory indicators were found to be the risk factors of renal function recovery in AKI patients.

摘要:

Autoimmune diseases (ADs) increase the risk of non-Hodgkin’s lymphoma and contribute to poor prognosis of patients. However, the association between immunologic markers and clinical outcome has rarely been investigated. This study aims to analyze the prognostic value of pretreatment immunologic markers in newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively reviewed the data on 502 patients with DLBCL treated in our institution from January 2013 to March 2018. Survival functions were estimated using Kaplan–Meier method and Cox regression model. The 3-year progression free survival (PFS) and overall survival (OS) rates were 70.2% and 80.9%, respectively, and the complete remission (CR) rate was 78.1%. Among the patients, those with multiple (≥3) abnormal immunologic markers had significantly shorter 3-year PFS (52.7% vs. 77.3%, P<0.001) and OS (68.5% vs. 85.8%, P=0.001) than those without multiple abnormal immunologic markers. Multivariate analysis revealed that the presence of multiple abnormal immunologic markers and the elevated serum levels of lactate dehydrogenase were the independent adverse prognostic factors for PFS (P=0.008, P<0.001) and OS (P=0.003, P<0.001). Meanwhile, advanced Ann Arbor stage was an independent adverse prognostic factor for PFS (P=0.001) and age>60 years for OS (P=0.014). In conclusion, the immunologic status was closely related to lymphoma progression, and this study provides new insights into the risk stratification of patients with DLBCL.

Epidemic obesity in children and adolescents: risk factors and prevention

Eun Young Lee, Kun-Ho Yoon

《医学前沿(英文)》 2018年 第12卷 第6期   页码 658-666 doi: 10.1007/s11684-018-0640-1

摘要: The prevalence of obesity among children and adolescents (aged 2–18 years) has increased rapidly, with more than 100 million affected in 2015. Moreover, the epidemic of obesity in this population has been an important public health problem in developed and developing countries for the following reasons. Childhood and adolescent obesity tracks adulthood obesity and has been implicated in many chronic diseases, including type 2 diabetes, hypertension, and cardiovascular disease. Furthermore, childhood and adolescent obesity is linked to adulthood mortality and premature death. Although an imbalance between caloric intake and physical activity is a principal cause of childhood and adolescent obesity, environmental factors are exclusively important for development of obesity among children and adolescents. In addition to genetic and biological factors, socioenvironmental factors, including family, school, community, and national policies, can play a crucial role. The complexity of risk factors for developing obesity among children and adolescents leads to difficulty in treatment for this population. Many interventional trials for childhood and adolescent obesity have been proven ineffective. Therefore, early identification and prevention is the key to control the global epidemic of obesity. Given that the proportion of overweight children and adolescents is far greater than that of obesity, an effective prevention strategy is to focus on overweight youth, who are at high risk for developing obesity. Multifaceted, comprehensive strategies involving behavioral, psychological, and environmental risk factors must also be developed to prevent obesity among children and adolescents.
